Smart Idle Parameters
Battery Monitor and Engine Control Voltage
Description:
This parameter is used to determine the voltage trip
point below which the Battery Monitor and Engine
Speed Control System will automatically elevate engine
idle in order to maintain ideal battery system voltage.
The engine idle will only be increased if the vehicle is
stopped and the transmission is out of gear. If these
conditions are not met, the engine idle will not be
adjusted.
The engine idle will be increased to 1000 RPM, or will be
increased by an amount less than 1000 RPM if the Idle
RPM Limit parameter is programmed less than 1000 RPM
(see page ).
Note:
This feature requires the installation of a Neutral Switch
on J1/P1 terminal-62 (Input #12). Engine speed will only
be elevated when the transmission is in neutral.
Available:
All electronically controlled on-highway engines

Advantages:
Promotes additional battery life.
Disadvantages:
Slight effect on fuel economy if the engine idle is
elevated too often.
Recommendations:
✔ Set to 12.2 V for a 12 V system, and 24.5 V for a 24 V
system.
